I read from flysch to foal.  I'm no engineer so the flywheel is confusing.https://en.wikipedia.org/wiki/Flywheel  Compared to AM radio, FM has higher quality sound and travels a shorter distance. And the radio wave frequencies are much higher.AM frequencies range from about 535 to 1700 kHz (535,000 to 1,700,000 Hz) and FM is 88 to 108 MHz (88,000,000 to 108,000,000 Hz). FM waves vibrate faster than AM. https://en.wikipedia.org/wiki/FM_broadcastinghttps://en.wikipedia.org/wiki/AM_broadcasting  The formula for the f-number is actually very simple, but you'll probably never have to use it.So it may not be that f0.9 lets it more light than exists, but more so that the diameter of the opening is bigger than the distance to the sensor. Or something  f-number = focal length / diameter of the apertureI also can never remember how the focal length is measure on a lens, but the shorter ones are wide angle lenses and the longer ones are telephoto lenses. https://en.wikipedia.org/wiki/F-numberhttps://en.wikipedia.org/wiki/Focal_length  The word of the episode is "fly speck".  Use my special link https://zen.ai/thedictionary to save 30% off your first month of any Zencastr paid plan.   Create your podcast today! #madeonzencastr  Theme music from Tom Maslowskihttps://zestysol.com/  Merchandising!https://www.teepublic.com/user/spejampar  "The Dictionary - Letter A" on YouTube"The Dictionary - Letter B" on YouTube"The Dictionary - Letter C" on YouTube"The Dictionary - Letter D" on YouTube"The Dictionary - Letter E" on YouTube"The Dictionary - Letter F" on YouTube  Featured in a Top 10 Dictionary Podcasts list!https://blog.feedspot.com/dictionary_podcasts/  Backwards Talking on YouTube:https://www.youtube.com/playlist?list=PLmIujMwEDbgZUexyR90jaTEEVmAYcCzuq  https://linktr.ee/spejampar[email protected]https://www.facebook.com/thedictionarypod/https://www.threads.net/@dictionarypodhttps://twitter.com/dictionarypodhttps://www.instagram.com/dictionarypod/https://www.patreon.com/spejamparhttps://www.tiktok.com/@spejampar917-727-5757
